.SH "DESCRIPTION"
.PP
The pam_debug PAM module is intended as a debugging aide for determining how the PAM stack is operating\&. This module returns what its module arguments tell it to return\&.
.SH "OPTIONS"
.PP
auth=value
.RS 4
The
\fBpam_sm_authenticate\fR(3)
function will return
\fIvalue\fR\&.

cred=value
.RS 4
The
\fBpam_sm_setcred\fR(3)
function will return
\fIvalue\fR\&.
.RE
.PP
acct=value
.RS 4
The
\fBpam_sm_acct_mgmt\fR(3)
function will return
\fIvalue\fR\&.
.RE
.PP
prechauthtok=value
.RS 4
The
\fBpam_sm_chauthtok\fR(3)
function will return
\fIvalue\fR
if the
\fIPAM_PRELIM_CHECK\fR
flag is set\&.
.RE
.PP
chauthtok=value
.RS 4
The
\fBpam_sm_chauthtok\fR(3)
function will return
\fIvalue\fR
if the

\fBnot\fR
set\&.
.RE
.PP
open_session=value
.RS 4
The

.RE
.PP
close_session=value
.RS 4
The
\fBpam_sm_close_session\fR(3)
function will return
\fIvalue\fR\&.
.RE
.PP
Where
\fIvalue\fR
can be one of: success, open_err, symbol_err, service_err, system_err, buf_err, perm_denied, auth_err, cred_insufficient, authinfo_unavail, user_unknown, maxtries, new_authtok_reqd, acct_expired, session_err, cred_unavail, cred_expired, cred_err, no_module_data, conv_err, authtok_err, authtok_recover_err, authtok_lock_busy, authtok_disable_aging, try_again, ignore, abort, authtok_expired, module_unknown, bad_item, conv_again, incomplete\&.
.SH "MODULE TYPES PROVIDED"
